Notes (Tafseer)

5590. See the end of the last note. "Our Faith tells us that Allah will deliver us from all harm if we sincerely repent and lead righteous lives. You, Unbelievers, have no such hope. When the real adjustment of values is established, you will soon see whether we were in the wrong or you!"
